Encrypt PDF on Android
Encrypt PDF on your Android phone or tablet right in Chrome — no Play Store app, no account, and nothing to install. ContinuePDF works with the Android share sheet, Files by Google, and Google Drive, so you can encrypt your PDF from wherever it lives. The whole thing runs on your device, so it works well even on a slower connection.

What you can do with Encrypt PDF
Encrypting a PDF locks it with a password, so the document can only be opened by someone who knows it — protecting sensitive files when they are shared, emailed, or stored somewhere less secure.
Protect financial documents
Password-protect bank statements, tax returns, or payslips before sending them.
Secure an email attachment
Add a password so a confidential file is useless to anyone who intercepts the email.
Lock personal records
Encrypt medical results, contracts, or IDs kept on a shared or cloud drive.
Share on a need-to-know basis
Give the password only to intended recipients so others cannot open the file.
Encrypt PDF on Android without the Play Store
Play Store PDF apps tend to be ad-heavy, ask for broad storage permissions, and lock the actual encrypt feature behind a subscription. That is a lot to accept just to process one file, and it means giving an app ongoing access to your documents.
ContinuePDF runs in Chrome instead. There is no app to install and no special permission to grant — you simply pick your PDF from Downloads, Files by Google, or Google Drive, encrypt it, and the password-protected PDF saves back to Downloads where the Android share sheet can send it anywhere. Because the work is done on your device, your files are never uploaded.
Why choose ContinuePDF
No Play Store
Runs in Chrome — no app, no ads-heavy download, no broad permissions.
Drive & Files
Pull files from Downloads, Files by Google, or Google Drive.
Share sheet ready
Send password-protected PDF to any app via the Android share sheet.
Works on slow data
Processing is local, so it holds up on a weak connection.
Pro tip
Use a strong, unique password and send it to the recipient through a different channel than the file itself — for example, email the PDF but share the password by message or phone. Do not lose the password; without it, the file cannot be opened.
Frequently asked questions
What happens if I forget the password?
There is no back door — a forgotten password means the file cannot be opened. Keep the password somewhere safe, ideally in a password manager.
Does encryption protect the file everywhere?
Yes. The password requirement is part of the PDF itself, so any compliant reader on any device will ask for it before showing the contents.
Is there a Encrypt PDF app for Android?
You don't need one. Encrypt PDF runs in Chrome on Android. Add your PDF from Downloads, Files by Google, or Google Drive, and password-protected PDF saves to your Downloads folder — no Play Store app required.
Where does the file go after processing on Android?
Password-protected PDF is saved to your device's Downloads folder. From there you can open it in any app or send it with the Android share sheet.
Is ContinuePDF free to use?
Yes. ContinuePDF and all of its tools, including Encrypt PDF, are free with no signup required. Because documents are processed in your browser rather than on our servers, we can offer the full feature set at no cost.
